SHUCK-GLUING MACHINE.

SPECIFICATION forming part of Letters Patent No. 571,321, dated November10, 1896.

Application filed November 22, 1895. faerial No. 569,822. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM F. I-IUTCHIN- SON, of New York, in thecounty and State of New York,have invented certain new and usefulImprovements in Shuck-Gluin g Machines, of which the following is afull, clear, and exact description.-

My invention relates to improvements in that class of machines which areused in forming and gluing the shucks or Wrappers of that kind of boxeswhich have an internal tray and external shuck. I11 making shucks ofthis kind it is customary to form them from a long strip of paper, amachine being used which automatically shapes and glues a shuck-tube andthen cuts off the shucks to the required length. In using a machine ofthis sort, however, there are many shucks out which are not properlyglued and do not stick, and when the machine is stopped and againstarted there is a long strip of material which is not properly stuck orglued and is cut off in strips corresponding to the length of a shuck.

The object of my present invention is to produce a simple and efficientmachine for working up the odds and ends of materialprovided in themanner above described, which machine will properly glue the singleshucks and thus utilize what would otherwise be waste material.

To these ends my invention consists of cer tain features of constructionand combinations of parts which will be hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a longitudinal section of my machine on the line 1 1 of Fig.3. Fig. 2 is a de tail plan view of the mechanism for keeping the maingluing-wheel clean. Fig. 3 is a Fig. 4 is a broken side elevationillustrating the means of driving the feed and compression rolls. Fig. 5is a broken inside elevation of the doubling-guide. Fig. 6 is a planview of said guide. Fig. 7 is a cross section on the line 7 7 of Figs. 5and 6. Fig. 8 is a cross-section on the line 8 8 of the same figures.Fig. 9 is a cross-section on the line 9 9 of said figures. Fig. 10 is across-section on the line 10 10 of said figures, and Fig. 11 is across-section on 'the line 11 11 of said figures, the cross-sections inFigs. 7 to 11, inclusive, showing the various positions of theshuck-flap as it is turned and glued and the changing shape of thedoubling-guide.

The machine has a suitable frame 10, extending longitudinally acrosswhich are the guides 11 and 12, the former being longer than the latter,however, and being perfectly straight and U-shaped in cross-section,like the beginning of the guide 1.2, as shown in Fig. 7 The guide 11 isadapted to guide the doubled part of the shuck, which is straight andhas no flap, and the guide 12 is intended to double the flap andgradually bring it into contact with the body portion of the shuck.

. The shucks are carried longitudinally through and between the guides11 and 12 by feed-rolls 13, which are preferably rubbercovered and arearranged one above the other, as shown in Fig. 1, and the glued edge ofthe shuck is then carried between compressionrolls 14, which aresimilarly arranged, but are preferably of metal and are placed at therear end of the guide 12. The rolls 13 and 14 are carried bycross-shafts 15 and 16, journaled on the frame 10, and the upper .shafts16 are adjustable vertically in the usual manner in order that the rollsmay be held the desired distance apart. I The machine can be driven inany suitable way. As illustrated, it has a driving-pulley 17 (see Fig.3) on one of the shafts 15, and the several shafts 15 are provided withgrooved pulleys 18, which are connected by a belt 19, (see Fig. 4,) thisbelt running under one pulley, then over an idler 20, then beneath thenext pulley and over the next idler, and so on in a common well-knownmanner.

Near the front end of the machine andbeneath the guide 12 is a glue-potor fountain 21, in which turns a main glue-wheel 22, which is driven byagear mechanism 23, (see Fig. 3,) connecting with one of the shafts 15, V

(See Fig. 2.)

is secured to the sides of the fountain in a detachable manner, as shownin Fig. 2, and this cross-bar supports a cleaning-fork 27, whichstraddles one edge of the Wheel 22 and is adjustable back and forth onthe crossbar 26 by means of the keyhole slot 28 in the fork and theguide-screw 29 in the cross-bar. The shank 30 of the fork 27 isscrew-threaded and held in the slot 31 at one edge of the fountain 21 bymeans of the jam-nuts 3 and lock-nut 33. The above arrangement is notvery essential, however, and any suitable gluing and eleanin g mechanismmay be used.

The shucks 34 (see Figs. '7 to 11) have a flap 35 on one edge, which isscored in the usual manner and has to be doubled over upon the body ofthe shuck and glued; but guides 11 and 12 are cut away at the top, asshown at 36 in Fig. 3, in order that the shucks may be easily fed intothe guides, and the guide 11 is of U shape throughout its whole length,and the guide 12 is U-shaped on the start, as shown in Fig. '7, so thatthe iiap 35 can lie straight in it, as shown in the said figure.

lVhen the shuck is fed into the machine, it is caught by the rolls 13and carried along through the two guides, and the flap 35, as it passesover the wheel 24 and through the opening 25, is smeared 011 the underside with glue. The flap then enters the guide 12 again and passesthrough a cut or opening 38in the underside of the guide and thenengages the first curve or bend 39 (see Fig. 8) of the guide, whichcurve or bend is shaped to turn down the flap 35 slightly, and the guide12 gradually turns under more and more until at the point 40 (see Figs.3 and 9) the flap is turned farther than at the point 39, and the guideis still further contracted and turned under until at the point 41 theflap is farther doubled over, and, finally, at the point 42 the guideresumes its U shape, and the flap is here brought into contact with theunder part of the shuck-body (see Fig. 11) and is then carried out fromthe guide and between the compression-rolls 14, which squeeze this edgeof the shuck, and so firmly unite the flap to the body portion of theshuck. After leaving the compression-rolls the shuck is discharged upona ledge or shelf 43 at the rear end of the machine.

It will be seen from the foregoing description that the machine is onlyadapted to form shucks after they have been scored and cut, but that itdoes this very nicely and rapidly and firmly secures the flap to thebody portion of the shuck.

I am aware that gluing arrangements like that illustrated are in commonuse, also that it is not unusual to use guides to double over a portionof the shuck-body, and I do not claim such features broadly; but myinvention consists in the combination and arrangement of the two guides,the feed and compression rolls, and means for applying glue at the rightpoint.

Having thus described my invention, I claim as new and desire to secureby Letters Patent In a machine of the kind described, the com binationof the two guides essentially parallel with each other and of a generalU shape in cross-section, one of them having one side gradually bent todouble the flap of a boxshuck, feed-rolls between the two guides,compression-rolls at the discharge end of the doubling-guide, and meansfor applying glue to a box-flap through one side of the doublingguide,substantially as described.
